"The Avengers" won three awards, including the top prize, movie of the year. "Silver Linings Playbook" also collected three awards. Several stars, including show host Rebel Wilson, won a pair of prizes.

Rebel Wilson, who opened and closed the show wearing Iron Man-style armor, won the Breakthrough Performance for her work in "Pitch Perfect" and shared in the film's award for Best Musical Moment. Its stars, including Brittany Snow and Skylar Astin, opened the show with a mash-up medley.

"Avengers" writer-director Joss Whedon said as he accepted the top prize Sunday: "What's the opposite of humbled? We're Biebered to be standing here... This is the award that means the most to me. I am so grateful and very excited for 2015; we're going to bring you 'Avengers 2.'"

"The Avengers" also won best fight and best villain for actor Tom Hiddleston.

"Silver Linings Playbook" won best performance for stars Bradley Cooper and Jennifer Lawrence and best kiss for the on-screen smooch they share. Cooper accepted his award and the kiss prize. Lawrence was not at Sunday's ceremony.

Wilson, who opened and closed the show wearing Iron Man-style armor, won breakthrough performance for her work in "Pitch Perfect" and shared in the film's award for best musical moment. Its stars, including Brittany Snow and Skylar Astin, opened the show with a mash-up medley.

The MTV Movie Awards are as much about the anticipated movies of the upcoming summer season as they are about the finest films of last year. Fans vote online for the winners in traditional and irreverent categories such as best fight, best kiss and best shirtless performance.

Hollywood has increasingly used the fan-driven MTV Movie Awards as a platform to promote its summer product. This year, the show was moved up from June to April to incorporate the entire blockbuster season, which begins in early May.

Honorees and presenters represent upcoming movies, and the ceremony is typically peppered with commercials for forthcoming films and DVD releases.

Emma Watson, a star of this summer's "The Bling Ring," received the Trailblazer Award.

"For those of you sitting here tonight who don't think I'm funny, I'll be happy to fight you in the parking lot after the show," said Ferrell, who is currently at work on "Anchorman 2," slated for release later this year.

Jamie Foxx was a double winner, too. He shared the best WTF moment award with Samuel L. Jackson for their scenes together in "Django Unchained," and later thanked his daughter, parents and siblings in the audience as he accepted the Generation Award for his career in film.
